- Great motherboard - Stefan, 22 June 2017
It is a great motherboard for the price. I held off on writing this review because of severe compatibility issues with high speed ram. Since the latest bios 2.6, I have been able to run my memory stable at 3066mhz, cl16 without a problem. I was only able to achieve a 4ghz clock on the cpu (1700), and you can forget about too high voltages because the vrm's are not that strong.
Pros:
Incredible value and feature set.
2x m.2 slots
Great potential with tons of expand-ability.
Cons:
Since the update nothing worthy of being mentioned, except that the vrm's are definitely only 3 phase and anything over 145W gave me unstable power delivery (1.475V or higher)
